Cell-autonomous inflammation of BRCA1-deficient ovarian cancers drives both tumor-intrinsic immunoreactivity and immune resistance via STING

Christian Iseli, Julien Dorier, Mauro Delorenzi, Alizée Jéléna Grimm, Marco Mina, George Coukos, Alexandre Harari, Giovanni Ciriello

In this study, we investigate mechanisms leading to inflammation and immunoreactivity in ovarian tumors with homologous recombination deficiency (HRD). BRCA1 loss is found to lead to transcriptional reprogramming in tumor cells and cell-intrinsic inflammat ...

Neutrophils suppress tumor-infiltrating T cells in colon cancer via matrix metalloproteinase-mediated activation of TGF beta

Marc-Olivier Sauvain, Freddy Radtke, Mauro Delorenzi, Nadine Fournier, Markus Germann, George Coukos, Amber Dawn Bowler

High T-cell infiltration in colorectal cancer (CRC) correlates with a favorable disease outcome and immunotherapy response. This, however, is only observed in a small subset of CRC patients. A better understanding of the factors influencing tumor T-cell re ...

Antiangiogenic immunotherapy suppresses desmoplastic and chemoresistant intestinal tumors in mice

Matthias Lütolf, Mauro Delorenzi, Laureline Wetterwald, Sina Nassiri, Michele De Palma, Mario Leonardo Squadrito, Nikolche Gjorevski, Alan Nicolas Thierry Guichard, Simone Ragusa, Borja Prat Luri

Mutations in APC promote colorectal cancer (CRC) progression through uncontrolled WNT signaling. Patients with desmoplastic CRC have a significantly worse prognosis and do not benefit from chemotherapy, but the mechanisms underlying the differential respon ...

Type I interferon/IRF7 axis instigates chemotherapy-induced immunological dormancy in breast cancer

Mauro Delorenzi, Thibaut François Hugo Richard, Yu-Ting Huang

Neoadjuvant and adjuvant chemotherapies provide survival benefits to breast cancer patients, in particular in estrogen receptor negative (ER-) cancers, by reducing rates of recurrences. It is assumed that the benefits of (neo)adjuvant chemotherapy are due ...

Endothelial Calcineurin Signaling Restrains Metastatic Outgrowth by Regulating Bmp2

Mauro Delorenzi, Laureline Wetterwald, Nadine Fournier, Sina Nassiri, Borja Prat Luri

Calcineurin/NFAT signaling is active in endothelial cells and is proposed to be an essential component of the tumor angiogenic response. Here, we investigated the role of endothelial calcineurin signaling in vivo in physiological and pathological angiogene ...

Differential regulation of RNA polymerase III genes during liver regeneration

Felix Naef, Philippe Jacquet, Nicolas Jean Philippe Guex, Jonathan Aryeh Sobel, Cristian Carmeli, Olivier Martin, Irina Krier, Mauro Delorenzi, Nouria Hernandez, Bart Deplancke, Jacques Rougemont, François Mange, Laura Symul, Fabrice David, Sunil Kumar Raghav, Julien Delafontaine, Marion Leleu, Julia Catharina Cajan, Winship Herr, Kyle Gustafson, Maykel Lopes, Dominic Villeneuve, Ioannis Xenarios

Mouse liver regeneration after partial hepatectomy involves cells in the remaining tissue synchronously entering the cell division cycle. We have used this system and H3K4me3, Pol II and Pol III profiling to characterize adaptations in Pol III transcriptio ...

RasGRP1 is a potential biomarker for stratifying anti-EGFR therapy response in colorectal cancer

Mauro Delorenzi, Delphine Yvette L Grun

Colorectal cancer (CRC) is the third most frequent neoplastic disorder and is a main cause of tumor-related mortality, as many patients progress to stage IV metastatic CRC. Standard care consists of combination chemotherapy (FOLFIRI or FOLFOX). Patients wi ...

Mutant CTNNB1 and histological heterogeneity define metabolic subtypes of hepatoblastoma

Paolo Angelino, Olivier Michielin, Mauro Delorenzi, Etienne Meylan, Jessica Christine Vazquez, Stefania Crippa, Pierre-Benoit Bernard Ancey

Hepatoblastoma is the most common malignant pediatric liver cancer. Histological evaluation of tumor biopsies is used to distinguish among the different subtypes of hepatoblastoma, with fetal and embryonal representing the two main epithelial components. W ...

RIP4 inhibits STAT3 signaling to sustain lung adenocarcinoma differentiation

Paolo Angelino, Mauro Delorenzi, Nadine Fournier, Etienne Meylan, Johanna Pauline Chiffelle, Jawahar Kopparam, Alessandra Piersigilli

Loss of epithelial differentiation and extracellular matrix (ECM) remodeling are known to facilitate cancer progression and are associated with poor prognosis in patients with lung cancer. We have identified Receptor-interacting serine/threonine protein ki ...

FOXC2 and fluid shear stress stabilize postnatal lymphatic vasculature

Mauro Delorenzi, Yan Agalarov, Esther Bovay, Nadine Fournier

Biomechanical forces, such as fluid shear stress, govern multiple aspects of endothelial cell biology. In blood vessels, disturbed flow is associated with vascular diseases, such as atherosclerosis, and promotes endothelial cell proliferation and apoptosis ...

CL9/9L-beta-catenin Signaling is Associated With Poor Outcome in Colorectal Cancer

Michel Aguet, Mauro Delorenzi, Norbert Wiedemann, Sylvie André Baflast, Pascale Anderle Pedone, Frédérique Baruthio, Andreas Eduard Moor, Patrick Rodriguez

BCL9/9L proteins enhance the transcriptional output of the beta-catenin/TCF transcriptional complex and contribute critically to upholding the high WNT signaling level required for stemness maintenance in the intestinal epithelium. Here we show that a BCL9 ...

The consensus molecular subtypes of colorectal cancer

Paolo Angelino, Mauro Delorenzi, Douglas Hanahan, Anguraj Sadanandam, Krisztian Homicsko, Sarah Gerster, Xin Wang

Colorectal cancer (CRC) is a frequently lethal disease with heterogeneous outcomes and drug responses. To resolve inconsistencies among the reported gene expression-based CRC classifications and facilitate clinical translation, we formed an international c ...
